일반 설명
2-tert-Butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (BEMP) is a phosphazene base. BEMP participates in the mild base catalyzed nucleophilic ring opening of N-sulfonyl aziridines. BEMP supported on polystyrene (PS-BEMP) has been reported as an efficient catalyst for the ring-opening of epoxides with phenols. BEMP is about 2000 times more basic and also much more sterically hindered than DBU (l,8-diazabicyclo[5.4.0]undecene).
애플리케이션
2-tert-Butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (BEMP), a organic phosphorine base may be used in the following studies:
- Synthesis of a 2,3-dihydrobenzo[1,4]dioxepin-5-one.
- As catalyst in the alkylation reactions of carbon acids.
- As organocatalyst in the controlled "immortal" ring-opening polymerization (iROP) of six-membered cyclic carbonates.
